The research was conducted to analyze the effect of contextual approach learning with local potentials on critical thinking skills and influencing factors. This research used quasi-experimental. The design used is a nonequivalent control group design. This research was conducted at Junior High School 10 Magelang. The subjects were students of class VIIF as the control class and class VIII G as the experimental class. The experimental class was treated with a contextual approach containing "getuk" local potential, while the control class was treated with a scientific approach. The data were collected through non-test with the observation of learning implementation and test with pretest-posttest to measure critical thinking skills. Data analysis was conducted using the Independent Sample T-Test dan effect size. The results found that the contextual approach containing the local potential “getuk” affected the critical thinking skills of grade VIII students of Junior High School 10 Magelang. This is indicated by the results of the Independent Sample T-Test, the value of Sig (2-tailed = 0.016) <½ α (0.05) is obtained, so Ho is rejected. The influence of the contextual approach with local potential "getuk" has medium criteria with an effect size coefficient of 0.76. This big influence is caused by factors. First, the contextual approach plays a role in the learning process to link contextual material contained in local potentials with the knowledge being taught that can train critical thinking skills. Second, the local potential of getuk which is integrated into teaching materials in the form of videos and worksheets can be an object to facilitate critical thinking skills. © 2022 American Institute of Physics Inc..
